To all whom it may concern:

Be it known that I, JOHN E. HUTZEN, a citizen of the United States, andresident of Chicago, in the county of Cook and State of Illinois, havemade a certain new and useful Invention in Roll-Reducing Machines; and Ideclare the following to be a full, clear, and exact description of thesame, such aswill enable others skilled in the art to which itappertains to make and use the invention, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure l is a side view of the machine. Fig. 2 is a horizontal sectionalview. Fig. 3 is a vertical longitudinal section. Fig.

4 is a horizontal section of the reducing roll.

Fig. 5 is a detail sectional view on the line 5-5, Fig. 1.

This invention has relation to roll machines designed chiefly forreducing cereals to filament form, and it consists in the novelconstruction and combinations of parts, as hereinafter set forth.

In the machine described, the channeled cutting rolls consist ofremovable thin cylinder-edged disks of larger and smaller diameter,compressed solidly together on their shafts from eye to perimeter bymeans of suitable bracing collars, such rolls working together so thateach set of rolls gives ofi two sets of filaments, the material beingprepared by the action of crushing rolls over the disk rolls. Eachdisk-roll is easily taken apart for repair, and when the disks areassembled on the roll shaft, they are designed to be solidly heldtogether, and especially at their peripheral portions, because of theirthin. character. The adjustment of the rolls toward and from each otheris of positive character in either di- 7 reetion, and is so designedthat after the adjustment as to the thickness of the filament, this sizewill be maintained evenly throughout its length. In the accompanyingdrawings, illustrating the invention, the letter a designates a hopper,in or below which is placed a pair of smooth steel feeding andcrushing"- rolls 6, 6, designed to crush the-grain, after it has beenput in proper condition for shredding,

by boiling or soaking. Scrapers c, are

an excellent purpose.

9, g, designate parallel'steel shafts, which are the basis of thecutting rolls f, f; and

on these shafts are seated the roll bodies composed of annular steeldisks h, andis, arranged in series in the following manner. The disksare circular, and are made of thin sheet steel, saw steel being easilyavailable for the purpose. The thickness of steel preferred is about onethirty-second of an inch.

The disks are bored to provide proper openings whereby they are seatedon the shaft, and the openings may be provided 'with seats for placing akey or feather to pre- Venttheir turning on the shaft. The disksemployed are designed to be of two diameters, the sm ller disks 70,being about five inches in diameter, and the larger disks it, about fiveand one-eighth inches; the difference betweenthe diameters being aboutoneeighth of an inch more or less; These disks are arranged in analternative manner on the shaft, so that a small disk is seated betweentwo large disks, and its circumferential edge forms the bottom of asmall channel whereof the parallel circumferential portions of thelarger disks form the side walls, and the terminal rectangular cuttingedges of which, because of the hardened character of the disk surface,are designed to serve Such channel is therefore circumferential, havinga depth of about a sixteenth of an inch, more or less, and a width ofabout a thirty-second of an inch, more or less. The cutting disks andthe fine channels between their circumferences are designed to operateupon the grain '10 gage a thread of the shaft;

In order to preventundue frict1on between the cuttingedges of the cutting disks 7 where they are designed to intermesh, thin'first paper disks may be interposed between the large and small disks ofthe series.

The working ends ofthe teeth t, which engage the edges of the smaller disks teeth securelyand in the bottoms of the channels, under of the roll, are designed tohave a concave curvature corresponding to that of the diskcircumference. The concave end of eachtooth therefore terminates in anacute edge of nearly the width of the channel, and is designed to doefficient work in the 'dis charge of the filament of material thereom.In order toprovide for exact adjustment of the cutt' g rolls, eachjournal bearing box 6, is provided with a boss (2', which is providedwith a threaded aperture to. en-

This exact alinement is of the importance,because of the fineness or smallness of the elements of the rolls, whichrequires elimination of angular variation, so that the edges of all thelarger disks shall exactly meet alongthe rolls, and in this way dividethe cereal into filaments by'such meeting without intermeshing. Angularvariation in the alinement of the rolls will precereal material,
